REFRIGERATOR.

Application ined `.aannam 25; 19.23. serial No. 614,878.

My invention relates to improvements in refrigerators and while the present disclosure is directed more particularly to one of the type Aused in stores and the like for containing meat and vother perishable produce,

it will be understood that the invention is not restricted to this particular field.

One object of the invention is to provide a refrigerator having novel means for circulating cold air therein, whereby to produce more eiiective refrigeration.

A further object is to provide a refrig-- erator having a pan at its lower end Vfor retaining a quantityof ice water supplied thereto from a ydrip pan for -the ice compartment,^thereby further assisting in producing an extremely low tempera-ture within the refrigerator. L Y

r,With the :foregoing in View, the'invention resides in the novel subject matter hereinafter described and claimed, the .description being supplemented by the accompanying drawings. f' Y Figure v1vis a vertical longitudinal sectional view through a refrigerator constructed in accordance with my invention.

Figure 2 is a vertical transverse sectional `View as indicated by line 2%2 ofFig 1.VV

`Figures 3 -and 4 are horizontal sectional views on lines 3-3 and ll-'t-of Fig. l.V L A Figure 5 is ahorizontal sectionalview cut on a lower plane, as'indicated byv line 5-5 ofFigfl. Y Y l Figure is an enlarged vertical sectional view through :the water sealedoverflow from the water retaining pan. Y l

Figure 7 is a -horizontal sectional view. as indicated by line'7-7 of F ig. 6. Y

The wallof the .refrigerator casingv is preferably ormedof inner and outer walls ly and 2 spaced apart to .provide a dead airinsulating space 3 and while these walls k1 and 2 have been shown of solid constructiomit willv be kunderstood that they may berof` any suitable construction desired. The space betweenithe-two walls is filled with cork 'or any suitable material which Jforms a good insulation. The lower end of the refrigerator is provided with a suitable iooror bottom 4 and with a false bottom 5 spaced beneath the same, a water retaining pan 6 being disposed between the two bottoms and being substan tially co-eXtensive therewith. This pan receives the drippings from the ice and I provide a unique form of water sealed overflow which permits the maintenance of a constant level of water in said pan. VThis overflow is detailed in Figs; 6 `and 7 to. which reference is no-wmade more particularly.

A vertical water discharge pipe 7 lwhichl may be connected to any desired drainl pipe or to a sewer, passes through vvthe bottom vof 'the' pan 6 and'has a liquidtight connection therewith, sai'd pipe being yprovided at its interior with a water cup whose sides are spaced from the pipe,-said cup being preferably or" square form with :its corners se:-

cured to the pipe as detailedin Fig. 7. An

'inner relatively small water discharge pipe 9 is received in andspaced romthe pipe 7, the lower end oil said pipe 9 being received in the vwater cnp 8' while the npper end ror "said pipe 9 is provided with one or more downturned water inletarms 10V which extend to a plane near the bottom of the pan 6. lIn the construction show-n, a sleeve 11 frictionallyy surrounds the pipe 7 .and rests at its lower end upon a rubber washer-or the like 12, while the upper-end of said sleeve hasV a'fliqnid-tight connection with' the up cup 801i' course overflows intothe rdischarge pipe 7 .I Whenever desired, the -pipe =9 and the sleeve l1 may' bebodily removed'for cleaning, -for which purpose I Ihave shown a removable section 13 in lthefl'oore. Y Y

The interiorof ythe Yrefrigerator is'divider by a horizontal drip panV 14 into annpper ice compartment 15I and a'lower refrigerating compartment 16; The pan is preferably rather shallow land may well ybeprovided at its upper edge'with ali-outwardly extend-ing horizontal'flange 17 to rest onan 'appro-V priate supporting'led'ge 118. Also ifdesi'red',

the flange 17- may beformed at its outer redge with an upstandingv flange 19 over which the metal lining 20 for the refrigerator may lapy-insuringf that all Lvdrippin-gs from the-ice and condensate ori-"the walls ot vof conical members 21 having air circulating openings 22 in their apices. The'water Adripping into the pany will not overflow through the oaenines 22, as an outlet )i e e e P 23 which leads from said pan into the pan 6, has its inlet end at a suiliciently low level to prevent such an occurrence. Furthermore, water is prevented from ldripping directly into the openings 22 upon the ice, by the provision of a plurality of transversely arched ice supporting bars 24 which extend across the pan let and may have their ends supported upon and suitably secured to the flange 17. The bars 2e are preferably oi inverted Vshapc as shown.

The top of the refrigerator which i'ornled ot suitable upper and lower walls 25 and 2G spaced apart, is provided in its lower side with a plurality o'l' cavities which receive a plurality ot inverted funnel-shaped sheet metal members 27 having openings 28 at their apices which connect with the up,

per ends ot' upright air circulating pipes 29 disposed between the inner and outer walls of the refrigerator, the lower ends of these pipes being in communication with the refrigerating compartment 1G. Other air circulating pipes 30 between the inner and outer walls o the casing establish connnunication between vertically spaced portions oi the compartment 1G and the space between the tloor 4 and the water retaining pan (3.

The operation oit the refrigerator is as follows:

The cold air from the ice compartment descends through the space `between the supporting bars and the openings 22 into the food compartment 1G. Cold air also descends through the drain pipe 23 into the drain pan compartment (l. This leg or column of cold air in the pipe E23 is absolutely unlnolested and completely separated from the food compartment. This condition causes this leg of air to descend into the drip pan compartment 6 and to pile up therein, `the accumulated .ice water tending to keep theair l cool. This particular portion of cold air al'ter completely lilling the compartment then lills the pipes 30 and cornes out into theiood compartment i6 at a point a little above the bottom of the compartment, it then iningles with the cold air in the latter. As the warm air rises, it enters into pipes 29 through their open lower ends. These pipes 29 are in the insula tion between the refrigerator walls and, since separated from the cold ice compartment walls, permit the warm air to readily rise to the topoiI the i'unnels 27. The ice in the ice compartment cools the air above the ice, partly by radiation, but largely by i y conduction, and the air in the tunnels tends therefore to be cold.

This cold air, contacting with the warm air in the tops of the tunnels, :tor the. warn] air tends to rise, cools it, and it then gradually falls, but it falls as cold air, not warin, as it 'as on entering the tunnels. The amount oi the incoming warm `air being' small in comparison to the siae ot the ice compartment root or top, it desirable that it should not spread over the whole top, and therefore the tunnels are used to hoop it collected in a small space and to allow it to contact with restricted cold air, until it is cooled.

By providing the construction shown and described, or a substantial etpiivalent there` oi?, a reiirigerator is provided which is higl1- ly etlicient. As excellent results have been obtained .troni tho general arrangement shown and described, this arrangennnt may well be followed, but within the scope oi:l the invention as claimed, numerous changes may ot' course be made.
